Eagle Cutting Tool SC400-031-I Cobalt Stub Drill 31/64

Product Description

The EAGLE CUTTING TOOL SC400-031-I is a 31/64 inch cobalt stub drill designed for high-speed drilling in demanding trade and industrial applications. Cobalt construction provides superior heat resistance and cutting durability compared to standard high-speed steel, making it well suited for drilling through tough materials such as stainless steel, cast iron, and hardened alloys. The stub-length body offers increased rigidity and reduced deflection, which is especially valuable when drilling in confined spaces or when hole location accuracy is critical. Machinists, pipefitters, and fabricators working in mechanical and industrial settings are the primary users of this bit.

This stub drill is used in production machining, maintenance repair, and fabrication environments where short-flute geometry improves stability and control. The 31/64 inch diameter suits applications requiring a precise undersized or finish hole before reaming, as well as direct through-hole drilling in metal plate and structural components. It is appropriate for use in drill presses, milling machines, and hand-held power drills with adequate chuck capacity.

Key Features

• Cobalt construction delivers high heat resistance for drilling hard metals and abrasive materials
• Stub-length flute design increases rigidity and minimizes deflection during drilling
• 31/64 inch diameter suits pre-ream and through-hole applications in metal fabrication
• Compatible with standard drill chucks on drill presses, mills, and power drills
• Minimum order quantity of 1 allows single-unit procurement for service and repair work

Compatibility

Designed as an OEM-style replacement and standard-use cobalt stub drill for trade and industrial drilling applications in metal and similar hard materials.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with proper drilling technique and tooling speeds. Secure the workpiece firmly before drilling and ensure the drill chuck is tightened correctly to prevent slippage. Use appropriate cutting fluid or coolant when drilling hard metals to extend tool life and maintain hole quality. Follow shop safety standards and applicable workplace safety codes when operating drilling equipment.
